Normally I have always taken the

**Natural Numbers**to start at 1 and not to include**zero**.**Natural Numbers**are 1,2,3,4,5, [] and Whole**numbers**are 0,1,2,3, According to Wikipedia: In mathematics, a**natural number**is either a positive integer (1, 2, 3, 4, ) or a non-negative integer (0, 1, 2, 3, 4, ).Also know, why is zero not a counting number?

**Zero**is known as the neutral integer, or the whole

**number**that comes in the middle of the positive and negative

**numbers**on a

**number**line.

**Zero**does

**not**have a positive or negative value.

**Zero**is however considered a whole

**number**, which in turn makes it an integer, but

**not**necessarily a

**natural number**.

## What is the difference between a natural number and a whole number?

**Natural Numbers**are also called counting

**numbers**. Zero is the only

**whole number**which is not a

**natural number**. It is represented by 0. "Zero is the only

**difference between natural and whole numbers**."

2

## What is the highest whole number?

So, 0, 1, 2, 3,….,10 are called

**whole numbers**. So, 1 is the smallest natural**number**and 0 is the smallest**whole number**. But there is no**largest whole number**or natural**number**because each**number**has its successor. Every**whole number**is made up of one or more of the symbols 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9.3

## Is is a whole number?

**Whole Number**. A

**whole number**is a member of the set {0,1, 2, 3, …}. It is either one of the positive integers (natural

**numbers**) or zero. The set of

**whole numbers**is exactly equivalent to the set of non negative integers.

4

## Are all natural numbers are whole numbers?

**Natural numbers**are the set of positive integers, that is, integers from 1 to ∞ excluding fractional n decimal part. They are

**whole numbers**excluding zero.

**Natural Numbers**are

**also**called counting

**numbers**. Zero is the only

**whole number**which is not a

**natural number**.

5

## What is the meaning of a whole number?

**Whole numbers**are positive

**numbers**, including zero, without any decimal or fractional parts. They are

**numbers**that

**represent whole**things without pieces. The set of

**whole numbers**is represented mathematically by the set: {0, 1, 2, 3, 4, 5}.

6

## What is the meaning of odd number?

An

**odd number**is an integer which is not a multiple of two. If it is divided by two the result is a fraction. One is the first**odd**positive**number**. The next four bigger**odd numbers**are three, five, seven, and nine. Some sequential even**numbers**are: {0,2,4,6,8,10,12,14,16}7

## What is natural numbers and their opposites?

1,

**2**,**3**, etc.). Fractions and negative numbers are not natural numbers, but are the opposite of natural numbers. These negative numbers can be called integers. Zero is considered an integer (it is not a fraction or irrational number).8

## What is the definition of a composite number?

**Composite Number**. more A whole

**number**that can be divided exactly by

**numbers**other than 1 or itself. Example: 9 can be divided exactly by 3 (as well as 1 and 9), so 9 is a

**composite number**. But 7 cannot be divided exactly (except by 1 and 7), so is NOT a

**composite number**(it is a prime

**number**).

9

## Why is 0 a whole number and not a natural number?

Zero is known as the neutral integer, or the whole

**number**that comes in the middle of the positive and negative**numbers**on a**number**line. Zero does**not**have a positive or negative value. Zero is however considered a whole**number**, which in turn makes it an integer, but**not**necessarily a**natural number**.10

## What is the definition of an even number?

An

**even number**is an integer which is "evenly divisible" by two. This means that if the integer is divided by 2, it yields no remainder. Zero is an**even number**because zero divided by two equals zero, which despite not being a natural**number**, is an integer.**Even numbers**are either positive or negative.11

## Is the number 0 a real number?

A

**real number**may be either rational or irrational; either algebraic or transcendental; and either positive, negative, or zero.**Real numbers**are used to measure continuous quantities.12

## Is a zero a number?

**0**(zero) is both a

**number**and the numerical digit used to represent that

**number**in numerals. The

**number 0**fulfills a central role in mathematics as the additive identity of the integers, real

**numbers**, and many other algebraic structures. As a digit,

**0**is used as a placeholder in place value systems.

13

## Do set of positive real numbers include zero?

In mathematics, the set of

**positive real numbers**, , is the subset of those**real numbers**that are greater than**zero**. In a complex plane, is identified with the**positive real**axis and is usually drawn as a horizontal ray. The**real positive**axis corresponds to complex**numbers**.14

## Do whole numbers include zero?

The

**whole numbers**are the**numbers 0**, 1, 2, 3, 4, and so on (the natural**numbers**and zero). Negative**numbers**are not considered "**whole numbers**." All natural**numbers**are**whole numbers**, but not all**whole numbers**are natural**numbers**since zero is a**whole**number but not a natural number.15

## Is the number 0 a rational number?

Moreover, we know

**0**can be written as**0**/1, we observe that both**0**& 1 are integers and the denominator i.e. '1' ≠**0**. So we conclude that '**0**' is a**rational number**and not irrational. We conclude that all whole**numbers**, all Positive and Negative**Numbers**are**rational numbers**.16

## Why is zero an even number?

Zero is an

**even number**. As a result, zero shares all the properties that characterize**even numbers**:**0**is divisible by 2,**0**is neighbored on both sides by odd**numbers**,**0**is the sum of an integer (**0**) with itself, and a set of**0**objects can be split into two equal sets.17

## Is a repeating number irrational?

**Recurring**decimals such as 0.26262626…, all integers and all finite decimals, such as 0.241, are also rational

**numbers**. Alternatively, an

**irrational number**is any

**number**that is not rational. It is a

**number**that cannot be written as a ratio of two integers (or cannot be expressed as a fraction).

18

## What is the first natural number?

Depending on the mathematician, the

**natural numbers**include: 1, 2, 3, 4, 5, . . . (also called the positive integers), or 0, 1, 2, 3, 4, 5, . . . (also called the nonnegative integers or whole**numbers**).19

## Why is zero not a prime number?

**Zero**is

**not prime**, since it has more than 2 divisors.

**Zero**is even, since 0=2⋅0, and 0 is an integer. If we use "

**number**" in essentially any of the usual senses (integer, real

**number**, complex

**number**), yes,

**zero**is a

**number**.

**Zero**is

**not a prime number**as

**prime numbers**are defined for integers greater than 1.
